A weak disturbance will bring light precipitation to southern portions of the Tennessee Valley late tonight into early Wednesday morning. Surface temperatures at or just below freezing could support some very light accumulations of sleet, ice or snow. A few localized slick spots may develop around daybreak, primarily (on) bridges and overpasses, and elevated surfaces. Use caution in these areas late tonight into the Wednesday morning commute. Slow down and allow extra time to reach your destination.
